Makes the foam roller seem like child's play. This thing brought tears to my eyes. It's like using a barbell as a roller.

It's only big enough for the quads (can't roll out your back, etc.) but it hits much, much deeper than a foam roll. Plus, the way it's built...it appears that it will far outlive a regular foam roll.

That quadballer looks much better than the foam roller. I don't even use my foam roller that often and it already turned into an hourglass shape. Is the quadballer wide enough to roll your lower and upper back? It looked like the wheels on the side might get in the way.
